Note:
– Emergency operation circuit required including between CPUs or for a separately connected Gateway
– Emergency operation circuit and emergency supply are not designed as a loop line
– Emergency supply via separate cable or C-Bus feedback

Power supply (24V)

Fire & Security Products
Siemens Building Technologies Group
Options:
B3Q321 (Fire department control terminal)
B3R051 (Parallel indicators)
E3I040 (LON interface)
Printer, paging system/pager
max. 1000m per Loop with ø 0.6mm (incl. return line)
max. 1800m per Loop with ø 0.8mm (incl. return line)
Control unit CC11/CI11
When planning a system the following condition must be complied with:
At least one operating unit must comply with standard EN54, i.e. it must be equipped with
emergency operation and emergency power supply.
EN54 requirements:
Communication as loop line
Operating units also with emerg. operation
second de-coupled 24V supply
The number of wires in the connection cable depends on the application and the dis-
tances between the stations:
Is the operating unit supplied with 24V from the control unit or autonomously?
Is an emergency power supply provided according to EN54?
Is the emergency operation circuit (emergency operation) installed?

Operating units AlgoPilot B3Q... are designed for the voltage range 18..45V
The maximum current at 24V is 400mA
Max. length of line (approximate):
for cables ø 0.8mm
for cable cross-section 1mm
The current consumption for the options (fire department control terminal, parallel indi-
cator terminal, printer, paging system/pager) must be taken into account separately
